When people's understanding of LED displays is not thorough enough, companies and individuals are required to lead by example, inform people of the safety of LED displays, and eliminate people's potential misunderstandings about the insecurity of LED displays.

On the evening of August 31, local time, an open-air music festival in Germany encountered a strong storm, blowing down an LED display on the stage, causing 28 people to be injured. This type of accident is not the first time this year. On the 7th and 12th, an LED display screen of a bank fell due to improper installation and injured a child walking underneath the screen. The types of security incidents that occurred were different, but it was true that a security incident happened again on the LED display not long after a lapse of time. Even if it is not a product quality issue, the endless safety accidents still dampen people's confidence in using LED displays and make people question the safety performance of LED displays. Although the accident at the music festival has nothing to do with installation, it is also alerting end users to the need to strengthen the firmness of the LED display installation, reduce the impact of bad weather on the LED display, and enhance the safety of the LED display to avoid hurting the masses.

The LED display industry has a long history of development, but its security content issue started late and has been unable to take care of it. It was not until the past two years that the content security issue was raised by the industry, and content security was discussed and developed. On August 28, the Ministry of Industry and Information Technology and other departments issued guidance on strengthening industrial Internet security, clarifying the goal of initially establishing an industrial Internet security system by the end of 2020. As one of the subdivisions of Internet security, the issuance of this opinion is undoubtedly an official announcement to strengthen the security of the LED display content. It represents the strict inspection of the content of the LED display by various departments in the future, and also represents the LED display. The content security issue is forming a system. According to industry insiders, coupled with the recent Hong Kong incident and the 70th anniversary of the founding of the country soon, government departments will strengthen the content security of LED displays. This year will be a major turning point in the history of content security development.

However, domestic companies have long developed relatively mature control systems, which set up dual secret keys through mobile apps to ensure that content control does not fall into the hands of others. Moreover, real-name authentication is required when using the APP, so that relevant departments can accurately find the sender when an incident occurs, and punish the sender. LED screen companies can refer to and purchase products to enhance the safety of LED display content. Under the promotion of the country and the industry, the future LED content display will be able to develop at full speed and become one of the key directions of industry development.

From the above analysis, it can be concluded that the safety of LED display cannot be promoted by a company or a company in a certain field, but requires the joint cooperation of the entire LED display industry chain. Upstream manufacturers need to strengthen quality monitoring, downstream End users need to strengthen supervision and work together to maintain the safe image of the LED display.
